What is the least common approach Sophia can use to buy kiwifruit for her family?

The least common multiple of 3 and 4 is the correct choice because it represents the smallest quantity that can be divided evenly by both numbers. In this context, Sophia is looking for a way to purchase kiwifruit that accommodates both the requirements for 3 and 4 kiwifruits, perhaps to ensure that each family member gets an equal share or to fulfill a recipe requirement involving both quantities.

By calculating the least common multiple, which in this case is 12, Sophia can buy a total of 12 kiwifruits. This means she can evenly distribute them among the 3 family members (4 kiwifruits each) or the 4 family members (3 kiwifruits each). This approach is efficient as it minimizes waste and ensures everyone gets the necessary amount.

Other options, such as the greatest common multiple or the least common divisor, do not provide a workable solution for purchasing equal amounts that satisfy both quantities, and simply buying one package for each person would not be the most efficient choice. Hence, using the least common multiple is the most practical and effective strategy for her situation.
